When
ordering, please specify termination and packaging codes: e.g.
LPD4012-564MLC |
|
|
Termination: |
L = Silver-palladium-platinum-glass frit
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37). |
|
Packaging:
|
C = 7"
machine-ready reel
EIA-481 embossed plastic tape 1000 parts per full reel).
B = Less than full reel
In tape, but not machine-ready. To have a leader and trailer added ($25 charge),
use code letter C instead.
D = 13" machine-ready reel
EIA-481 embossed plastic tape. Factory order only, not stocked (3500 parts
per full reel). |

Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. When leads are connected in parallel, inductance is the
same value. When leads are connected in series, inductance is four times the value |
|
3 |
DCR is for each winding. When leads are connected in parallel, DCR is half the value. When leads are connected in series, DCR is twice the value. |
|
4 |
SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value. |
|
5 |
Isat:
DC current, at which the inductance drops the specified amount from its value without current. It is the current flowing in one winding or the sum of the current flowing in both windings. |
| 6 |
Irms, both windings: Equal current, when applied to each winding simultaneously, that causes a 40°C temperature rise from 25°C ambient.
See temperature rise calculation. |
| 7 |
Irms, one winding:
Maximum current, when applied to one winding, that causes a 40°C temperature rise from 25°C ambient.
See temperature rise calculation. |
| 8 |
Ambient temperature range: |
–40°C to +85°C with Irms current.
+85°C to +125°C with derated current. Derating curve |

Storage temperature range: |
Component: –40°C to +125°C
Packaging: –55°C to +80°C |
| 10 |
Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between. |
